Coins from Caucasus
The Caucasus s a region located at the border of Eastern Europe and Western Asia, situated between the Black Sea and the Caspian Sea and occupied in modern times by Russia, Georgia, Azerbaijan, and Armenia.

In ancient times, the area was home to the Armenians and the region of Colchis, named after the city of the same name.

The Transcaucasus region and Dagestan were the furthest points of Parthian and later Sasanian expansions, with areas to the north of the Greater Caucasus range practically impregnable. The mythological Mount Qaf, the world's highest mountain that ancient Iranian lore shrouded in mystery, was said to be situated in this region. In Middle Persian sources of the Sasanian era, the Caucasus range was referred to as Kaf Kof.
